Notably, the page links to a PDF of one of the critical sections of the Mo-Ho Chih-kuan, the work widely viewed as Zhiyi's most important . Previously you could get a CD with the first six chapters of he Moho Chih-kuan translated by Swanson from Kosei Publishing, but having looked on their website, it does not seem to be available anymore. I understand that a complete translation is supposed to be published, imminently by U. Hawaii, but I have not heard anything recently.

Only one of the works in this volume is directly Tiantai - its an outline by a 10th c. Korean monk, Chegkuan, who was invited to China to revive the Tiantai tradition that had apparently been lost there. While useful, this text has been criticized as misrepresenting Tiantai thought for the way in which the subject is presented. Still, useful for gaining an understanding of the Tiatai classification systems.

No offense to Cleary, but this is one of his worst published translations. Its a loose translation of the first chapter of Moho Chihkuan. It seems he started translating the text and then gave up. Its like he handed over a first draft that he never bothered to review. This really should not have been published. Its more or less incomprehensible.

Its a study and fairly detailed outline of what is often considered Zhiyi's second most important work, the Fa Hua Hsuan-i, a commentary on the Lotus Sutra through a structure based on its Chinese title. Swanson translates part of this in Tientai Philosophy. The outline here gives an idea about the rest of the text.

Also, this is a bibliography I put together years ago and had on my blog. Overlaps with many of the above:
